How to Form an LLC in Connecticut: $120 Fee and Official Steps

Putting together a Connecticut LLC is a fairly tight process: one formation filing, one ongoing agent appointment, and a small handful of annual tasks. The official Connecticut filing fee is $120, formation runs under Conn. Gen. Stat. § 34-247, and nearly everything happens online at business.ct.gov. The sections below detail every step, every state fee, and exactly where we fit.

The Case for a Connecticut LLC

An LLC is what most US small businesses choose because it offers liability protection with minimal formality. Among Connecticut small operations, you'll find LLCs across independent professionals, rental property holders, side-business operators, and small consultancies — the entity is light on paperwork and easy to maintain.

Connecticut LLC Filing Fee: $120

The official $120 filing fee is set by statute (Conn. Gen. Stat. § 34-243u(a)(3)) and covers the certificate of organization, including the registered agent appointment. We charge $199 for preparing and filing, agent coverage for the opening year included; from the first anniversary the agent costs $99/year.

The Certificate of Organization: Connecticut's Formation Document

Connecticut doesn't use "Articles of Organization." The formation document here is the Certificate of Organization (officially, Certificate of Organization, Limited Liability Company: Domestic), and the current official state form carries no form number. Under Conn. Gen. Stat. § 34-247, one or more organizers form the LLC by delivering that certificate to the Secretary of the State. (Yes, "Secretary of the State" with the extra "the" is Connecticut's official style.)

You can file two ways: online through business.ct.gov, which the state treats as the preferred channel, or by mail using the official fillable PDF. Online filings clear the fastest; overall timing varies with the state's workload.

Step-by-Step: Forming Your Connecticut LLC

1. Pick a compliant name. Connecticut requires an LLC indicator in the name and enough distance from names already on file. Run candidates through the state's business records search before you commit, and skip anything that implies you're a bank, insurance carrier, or government office unless you're actually licensed in that industry.
2. Appoint a Connecticut registered agent. Every LLC needs an agent with a place of business in Connecticut under Conn. Gen. Stat. § 34-243n, who has to sign an acceptance of the appointment; the LLC can't be its own agent. Our agent service handles the role (bundled into the formation price for twelve months, $99/year thereafter) and keeps your home address off the filing.
3. File the Certificate of Organization. Submit it online at business.ct.gov or mail the paper form, and pay the official $120 filing fee. The form asks for the LLC's name, principal office, registered agent details and acceptance, management structure (member-managed or manager-managed), and organizer signatures.
4. Adopt an operating agreement. Connecticut doesn't make you file one, but banks, courts, and your co-owners will all lean on it. It nails down ownership, profit allocation, decision rights, and exit procedures; without one, the state's default LLC rules fill the gaps, and they're rarely a good substitute for an actual agreement.
5. Get your EIN from the IRS. It's free at IRS.gov, takes about ten minutes, and you'll need it for banking, payroll, and federal filings. Don't pay an outside service for this.
6. Stay compliant year to year. Keep a registered agent on file continuously, file the $80 annual report during the January 1 to March 31 window each year, keep business and personal money separate, and stay current on federal and state taxes. Fall more than a year behind on annual reports and, after a three-month notice, the LLC can be dissolved by forfeiture, which suspends its liability protection until reinstatement.

Registered Agents in Connecticut

Connecticut's agent rule applies from day one and never lapses. The agent needs a real place of business in the state (a PO box alone won't do), a signed acceptance of the appointment, and the discipline to move lawsuits, tax notices, and state correspondence to you fast enough to protect response deadlines.

If you serve as your own agent personally, your residence address lands in the Secretary of the State's public records, searchable by anyone. Our address can go on the filing instead (no agent charge the first year if we organize the LLC, $99 annually later), and your personal mailing address never sees the public record.
